Method
- Start by prepping your brioche buns, cheddar, mayonnaise so the cooking goes quickly.
- Warm a splash of olive oil in a heavy pan over medium heat, then add the shallots and cook until soft and fragrant, about 4 to 5 minutes.
- Turn the heat up, add the meatball sub, and cook until deeply browned and aromatic.
- Fold in the butter lettuce and season generously; give everything a minute to come together.
- Off the heat, brighten it up with cracked black pepper and a final crack of pepper.
- Serve warm, ideally with something to soak up the sauce.
